In 2016 Stonewall commissioned the Centre for Family Research at the University of Cambridge to conduct a survey with young people who are lesbian, gay, bi or trans (or think they might be) on their experiences in secondary schools and colleges across Britain. Between November 2016 and February 2017, 3,713 LGBT young people aged between 11-19, including 267 living in Wales, completed an online questionnaire. This report represents the responses of these participants living in Wales. This study is the second report published by Stonewall Cymru, five years on from the School Report Cornerstone in 2012. It is the first to include the specific experiences of trans young people, reflecting Stonewall's decision to extend its remit to campaign for trans equality in 2015.
